Parts of a Refrigerator

You will not find too many houses that don’t have a refrigerator inside the kitchen. It’s been a must-have household appliance for many years now. A residential refrigerator is able to store your food at the best temperature, in order to stop spoilage and stop bacteria. The cycle of refrigeration works by transferring the heat from the inside of the unit to the outside, relying on the principles of evaporation and condensation.

The standard parts of a refrigerator are below. For questions or service call Best Boca Raton Appliance Repair:


The refrigerator compressor is both a motor and a pump, and it’s necessary for the circulation of refrigerant in the cooling system.
A compressor is an integral piece of a refrigerator. Homeowners should enlist a professional company if the compressor stops working.


The refrigerator condenser is located on the back exterior wall of the appliance and will help to release the heat built-up from within the refrigerator out into the surrounding air.


A refrigerator evaporator is housed on the inside of a refrigerator where absorbs heat contained inside of it, thereby reducing the temperature inside the unit.

Once the evaporator is not working, it’s time to hire a professional. You should not wait until it’s too late.

Expansion Device

Liquified refrigerant is carried through a capillary tube that acts as an expansion device to cool the gas inside, thereby turning it into a liquid.


A thermostat will regulate the current temperature in the interior of the refrigerator, engaging a new cooling period as necessary.

A thermostat inside of a refrigerator is very prone to breaking. Troubleshoot and hire a technician in Boca Raton for service right after an issue happens.

How Does Refrigeration Work?

1. Once the temperature in the interior of the refrigerator is above the set point sensors notify the compressor to engage, and the next cool down begins. The refrigerator collects the cool liquid refrigerant, pressurizes and condenses the liquid, and increases the temperature, in order to turn it into a gas.

2. The refrigerator compressor unit directs the hot gas in the direction of the condenser coils on the back of the unit, at which point it comes into contact with the lower temperature in the kitchen and returns to a liquid form.

3. The cooled liquid continues its trip towards the evaporator, pushing through the many coils within the appliance and top freezer.

4. The coolant then absorbs the warm air from within the appliance, lowering the temperature back to the desired final point.

5. The refrigerant then evaporates, and turns back into a gas form, and then returns to the compressor so it can continue the cycle.

Refrigeration is found in a number of applications and large appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By extracting warmth from a single location and relocating it to elsewhere the cycle of refrigeration will help cooling a house, provides a perfect environment for perishable food, and helps with the manufacturing and storage of a number of different common products and materials.
